Overview
... range ► Small die size Description The CMD282 is negative controlled, wideband GaAs MMIC 2-bit digital attenuator die which operates from DC to 40 GHz.
Each bit of the attenuator is controlled by a single voltage of either 0 V or –5 V.
The attenuator bit values are 4 dB and 8 dB, for a total attenuation of 12 dB.
The CMD282 has a low insertion loss of 1.
5 dB at 18 GHz and the attenuation accuracy is typically 0.
1 dB step error.
The CMD282 is a 50 ohm matched design which eliminates the need for RF port matching.
The CMD282 offers full passivation for increased reliability and moisture protection.
